The provided text offers a comprehensive overview of mass spectrometry (MS), detailing its fundamental principles and the mechanisms of various components. It explains how samples are ionized—either "hard," causing fragmentation, or "soft," preserving the molecule—and how mass analyzers separate ions based on their mass-to-charge ratio, with examples like quadrupoles, time-of-flight, and Orbitraps. The text then illustrates how detectors convert ion signals into a mass spectrum for data interpretation, including molecular and fragment ion peaks. Finally, it highlights the diverse and transformative applications of MS, ranging from proteomics and metabolomics to pharmaceutical development, clinical diagnostics, environmental monitoring, food safety, and forensic analysis.
